Thanks, Stefan! Just installed Clefos 7.9.2009, did some yum updates, and uname says 3.10.0-1160.36.2.el7.s390x. We are on a z14 ZR1, so I'm thinking only SMC-Dv1 for us. And it works well among my z/OS systems.
I've found 5 or more releases of smc-tools out in the wild, the most recent appears to be 1.7.0, which you released two months ago. Can't quite figure out what or how to download, and the docs you recommended point to a 1.2.1-level release. Found I can't VMRELOCATE a Linux system that has a pcifunction attached. Does the SMC and/or IP know while a socket is open that it has lost the pcifunction and automatically revert to normal HiperSockets (or other IP) communication? And after the VMRELOCATE completes, if a pcifunction is attached, can it restart using SMC-D?

Hi Rob, Yes, you can use smc_run to enable existing (binary) TCP applications to use SMC-D. Which specific version of ClefOS are you on, and what are the levels of the Linux kernel and smc-tools? If you have SMC-Dv1, check http://www.vmworkshop.org/2019/present/linuxsmc.pdf, especially p21. If you already have SMC-Dv2, check the presentation at https://community.ibm.com/community/user/ibmz-and-linuxone/viewdocument/2021-07-15-boosting-tcp-networking?CommunityKey=c1293167-6d93-448e-8854-3068846d3dfe&tab=librarydocuments. But, of course, I'll be glad to answer any questions, too!
